Definitions

  • the invention relates to a laminated pane with a sun protection coating and a coating that reflects heat rays, and the use thereof.
  • the DE19927683C1 discloses a laminated glass pane made of at least two glass panes and a transparent composite layer connecting them and with a sun protection layer that reflects rays outside the visible spectrum of solar radiation, in particular infrared rays, characterized in that the laminated glass pane is provided on its surface facing an interior with a further, from the sun protection layer is provided with a transparent coating (low-E layer) that is spatially separate and essentially reflects heat rays.
  • task of DE19927683C1 is to provide a laminated glass pane with sun protection properties, in which at low outside temperatures the heat absorption from the vehicle interior is greatly reduced by large-area glazing. The light transmission through the laminated pane is 31%, for example.
  • Glazing as used in sunroofs and sunroofs requires a light transmission of between 2% and 10% and a specific sun protection, characterized by the TTS value, which is a measure of the total heat radiation transmitted by the sun through the pane, and for example according to the ISO 9050 is measured.
  • TTS value a measure of the total heat radiation transmitted by the sun through the pane
  • IR-reflecting ie solar radiation controlling, functions have to be combined in laminated sunroofs and sunroofs.
  • IR-reflecting, ie solar radiation controlling, functions are provided by silver-based coatings on the inside of the outer pane or a polyethylene terephthalate film between two Polyvinyl butyral films achieved. Coatings based on silver have the intrinsic disadvantage that the reflection in the visible range of light is relatively high at at least 10%. This reflection has an influence on the reflection that is perceived by glazing on the interior side.
  • WO2013/127563A1 discloses another laminated pane having a solar control layer between the panes of glass and a low-e coating on the interior surface.
  • the Low-E coating is based on niobium, tantalum, molybdenum or zirconium.
  • U.S. 2015/165965 A1 , U.S. 2015/151675 A1 and EP 2090428 A1 each disclose composite panes with a Low-E coating.
  • the object of the invention is to achieve a constant light reflection of less than 6%, preferably less than 4%, perceived on the inside of the inner pane over the required range of preferred light transmission through the laminated pane of 2 to 10%. Another task is to achieve the lowest possible TTS value.
  • the laminated pane according to the invention comprises an outer pane with an outside surface and an inside surface, an inner pane with an outside surface and an inside surface and a thermoplastic intermediate layer which the inside Connects the surface of the outer pane to the outside surface of the inner pane, the laminated pane having at least one sun protection coating between the outer pane and the inner pane, which essentially reflects or absorbs rays outside the visible spectrum of solar radiation, in particular infrared rays, and the laminated glass pane on the interior side
  • the surface of the inner pane has a coating that reflects heat rays, the composite pane having a transmission index A of 0.06 to 0.08, the transmission index A (A value) being determined according to the following formula (I).
  • A tsp laminated glass pane / tsp LowE coated disc * TE where TL is the light transmittance and TE is the energy transmittance, each measured according to ISO 9050.
  • TL laminated glass pane designates the light transmission through the entire laminated pane.
  • TL LowE-coated pane refers to the light transmission through the inner pane including the coating that reflects heat rays.
  • the TL values can be set appropriately by choosing the tint of the components of the laminated pane, ie the inner pane, the outer pane and the intermediate layer.
  • the TE value is also determined by the choice of tint of the components of the laminated pane and also by the properties of the solar control coating and the heat-ray reflecting coating.
  • the corresponding values can be suitably selected by a person skilled in the art in order to achieve a transmission index A according to the invention.
  • the transmission values can also be determined according to standards other than ISO 9050, whereby the transmission index A changes only slightly.
  • such a composite pane has a low light transmission of 1 to 12%, preferably 2 to 10% and at the same time a low total transmitted thermal radiation (TTS) of in particular less than 50%, preferably less than 35%, particularly preferably less than 25% (measured according to ISO 9050), the light reflection of the laminated glass pane being less than 6%, in particular less than 4%.
  • TTS total transmitted thermal radiation
  • the light reflection here refers to the reflection at angles of 8°.
  • the values for light transmission (TL) and reflection (RL) refer (as is usual for automotive glazing) to light type A, i.e. the visible portion of sunlight at a wavelength of 380 nm to 780 nm of the visible spectrum of solar radiation, in particular infrared rays, means rays with a wavelength greater than about 800 nm.
  • the transmission index A is 0.06 to 0.08 and very particularly preferably 0.07 to 0.08.
  • the laminated pane is intended to separate an interior space, in particular the interior space of a vehicle, from the outside environment in a window opening.
  • the composite pane is a laminate and comprises a first and a second glass pane, which are referred to as the outer pane and inner pane within the meaning of the invention and are connected to one another via a thermoplastic intermediate layer.
  • inner pane refers to the pane facing the interior in the installed position.
  • the outer pane is the pane that faces the outside when installed.
  • the interior-side surface or inner side or inner surface
  • the outside surface is understood to mean that surface of the panes which faces the external environment in the installed position.
  • the surfaces of the glass panes are typically identified as follows: The outside of the outer pane is identified as side 1. The inside of the outer pane is referred to as side 2. The outside of the inner pane is referred to as side 3. The inside of the inner pane is referred to as side 4.
  • the interior surface of the outer pane and the outside surface of the inner pane face each other and are connected to one another by means of the thermoplastic intermediate layer.
  • the thermoplastic intermediate layer is formed by one or more thermoplastic films.
  • the thermoplastic films preferably contain polyvinyl butyral (PVB), ethylene vinyl acetate (EVA), polyurethane (PU) and/or mixtures thereof and/or copolymers thereof, particularly preferably polyvinyl butyral.
